STM32 MCUs Motor control

 Greetings.I started to study motor control with X-NUCLEO-IHM07M1 as following- MCU : STM32F302R8- PowerBD : X-NUCLEO-IHM07M1- Motor : Bull Running BR2804-1700Kv I just try to make STM32Cube IDE project using MC Workbench 6.4.1 (as described following screenshot image)but, Using ST Motor Pilot, When start command is on, just motor starts rotate 1 cycle, and stopped. Then, Status Occurs "FAULT_OVER" as following screen image And, main function is no codes for opreating because of just test with ST Motor pilot Can I ask help for what is problem?As Using MC Workbench Version 5.4.8, motor works.Is any difference between MC Workbench 5.4.8 and 6.4.1?  

Hello Everybody,Here are the software and boards in this case:1. MC workbench 6.3.22. NUCLEO-F401RE3. X-NUCLEO-IHM08M1I try to use the boards to obtain motor parameters. While other parameters were acquired normally, I encountered an issue with the Hall sensor parameters. When connected to two different motors, both returned errors indicating that H1 and H2 were not connected (as illustrated in the picture). However, the motor-board wiring is confirmed correct, and during motor rotation, normal voltage signals are present at the H1 and H2 pins of the motors. What could be causing this error in the Motor Profiler? Thank you. 

i am new to this BLDC motors and i am planning to build a 3-phase motor driver. attached the motor datasheet as well.Can anyone suggest a suitable driver for proof of concept for the attached motor specs.Link: https://www.maxongroup.com/medias/sys_master/root/9410429321246/Cataloge-Page-EN-260.pdf

I'm trying to control a BLDC motor attached to a STEVAL-ESC002V1 board though the UART connection, but so far without success.I updated the symbols and recompiled the supplied firmware to disable the PWM control and enable the UART. It compiled without errors and I was able to upload the BIN file to the board.Then using a terminal app on my laptop, I connected it using a USB-UART interface, to connector J2 on the board. The settings were 57600,8,1,Even, Noflow control.However after rebooting the board I was unable to get any output on the terminal, nor sending any commands to the board.Am I missing something ?  

Hello Everybody,I'm designing a motor control board using the STM32F405 MCU in an LQFP64 package. When using STMC board designer, I noticed only a limited selection of MCUs is available (please refer to the attached picture ).  Could you advise how to import my specific STM32F405 configuration into the tool? My goal is to use MCSDK for generating runnable code for this custom hardware. Thank you!

hi,Question 1: Should I tune PolPulse directly at the end of profile? Without any pre-operation, such as changing "FOC Mode" from "profiling" to another one?Question 2: Which phases are the PWM waves and currents from? Are there any requirements when I probe the signals?Question 3: What kind of "Pulse current goal" is the best goal? (1/4 short circuit current as a starting point, What is ending point?)  How to tune the PolPulse step by step?Here is the Profiling Result as a reference.Above all,  thank you!

Hello, I wanted to make auto-tune for my engine but there is no STEVAL-IPM30B power board in Motor Profiler tool. Only IPM-05, 10, and 15 are supported. Can I select IPM-15B board and run Motor Profiler with a physically connected IPM-30B?

hello i am making a custom STM32F405RGT6 board for A DUAL_BLDC_FOC VESC project that am making. i looked up how to programme the chip and it seems i needed to generate the code using STM32cubeMX  after instaling the X-CUBE-MCSDK embeded software package then opening it on STM32cubeIDE.  but i could't find it even after downloading the latest STM32F405RGT6 MCU PACKAGE and refreshing it multiple times; then i downloaded the X-CUBE-MCSDK6 and it seems the custom stm32F405RGT6 is not suported on the workbench; when i tried to import the (.zip) file it showed an error window. is the F405RGT6 motor control software no longer supported by the new version of the stm32cube? if so what version should i download to find it?   

Hello everybody, I would like to know when the VBUS voltage measurement is updated. I am using the functions to read the voltage:VBS_GetBusVoltage_dVBS_GetAvBusVoltage_VI am using the threads startMediumFrequencyTask, StartSafetyTask, and my own thread.At system startup, I want to load a buffer. But the measurements taken are incorrect or zero at the board startup.Is there any documentation on the acquisitions? MCSDK : 6.4.1Best regards.

I am using stm32G431C8U6 microcontroller and I use TB6612 motor driver to control two motors with encoders. I have enabled timer 2 channel 3 and 4 for PWM generation and Timer3 and Timer 4 for combined channel encoder mode. Also I have used Timer15 for timer interrupt. I need to move the two motors for a specific counter pulses (eg:25,000) and then I need to stop them when timer3 counter reaches to specified counter pulses. In the code it will not exactly stop at 25,000(specified counter pulses) and it will deviated  more than 25,000 (like 25,123,25,200) .Hence I have used PID function to mitigate this issue. I have enabled timer 15 for interrupt and in that interrupt function I have called back my PID function.In the PID function it is supposed to be that counter starts from 0 and every 100ms it will increment by one. For an example initially timer 3 counter at 0 and then next 100ms it will reach to one. Then I have designed the pid function as below,apply_pid(int error){int Kp=0

Hi Team,I have created folder for header file and it's path also included in the compiler path but it's grayed out.but I'm getting this error.Could you help me on this one.

My configuration:[VERSION]: MCSDK 6.3.2[TOOL]: MC Workbench, ST MOTOR PilotI am using the HSO on a custom board with an STSPIN32G4 at 15 kHz.The basic algorithm here should be the reciprocal of the bus voltage,  using LPF filtering for result. So the code should be modified as follows. Please help me confirm whether my understanding is incorrect or if there is indeed an error here? 

Hello,I am currently working with HSO for motor control and would like to clarify whether DPWM (Discontinuous PWM, 2-Phase PWM) is supported.In the Observer + PLL method, it seems possible to select discontinuous PWM by setting the modulation flag.However, I noticed that such an option does not appear to be available in HSO.Thank you in advance! 

I have a MC SDK project which works a treat, unless I reorder the windings on my motor.  It's configured for UVW / EN because that's how my driver works.  (TI DRV8311SA)The motors for my production build are a different phase order than I have been developing on.  Is it possible for me to reorder UVW in software so that my commutation is correct?  U and W need to be swapped physically for the motor to work.  Ideally this mapping would be changeable in the software somewhere? R

Hello,I am currently working on a project using MC Workbench 6.3.2 and the B-G431B-ESC1 board using the STM32G431 MCU to control a small motor, and I'm really struggling to wrap ny head around the current conversion formula. In various places in the code, it is explicitly stated that the current conversion formula is Current (digit) = [Current(Amp) * 65536 * Rshunt * Aop] / Vdd micro. However there are parts of this formula that confuse me. For one, the 65536 term seem to come from the adc conversion from voltage to digit. However the adc has only 12 bits, so I'm confused as to why this is not 4096 (2^12) instead. The other value that stumps me the amplification gain, Aop. It is stated to be 9.14 in the code parameters. But when i looked into the amplification parameters, i found the following line of code : LL_OPAMP_SetPGAGain(OPAMP1, LL_OPAMP_PGA_GAIN_16_OR_MINUS_15);Which seems to indicate the gain is 16? I'm not very familiar with the opamps peripherals so it is poss

Hello,I’m working on a FOC (Field Oriented Control) project to drive a PMSM (Permanent Magnet Synchronous Motor). I’m looking for an official STMicroelectronics development board that includes the following features:STM32-based microcontrollerSupports resolver and encoder input (preferably both)Gate driver outputs for external power stage (or integrated solution is fine)Fully compatible with FOC-based motor controlDoes ST offer such a motor control/inverter board?Please recommend any official ST hardware that fits these criteria. 

I used MotorControl Workbench_6.4.1 and used the Board designer to generate the simplest design for the sixStep inverter design.I choose STM32030K as the MCU and assigned back emf as the speed and position control and also configured the Phase voltage generation and M1 specification and every thing gets a green check mark. then I tried to build a project with the created inverter board file and when I select to generate the project, the MotorControl Workbench Just shows a blank screen and nothing happens. what's going on wrong?I have attached the inverted json file to the post.

Hello ST Community,I am designing a FOC motor controller using STM32G4 and want to use 3 separate ADCs (ADC1, ADC2, ADC3) in injected mode for simultaneous 3-phase current sampling.I know that some microcontrollers have triple-mode ADCs, which allow all three ADCs to start and finish simultaneously. My question is:1. When TIM1_TRGO is triggered, do all three ADCs start converting simultaneously, or is there a sequential order (ADC1→ADC2→ADC3)?2. What is the safest way to read an ADC for FOC algorithm?I am very new to this field, so please excuse me.Best regards

Dear member of ST community, I would ask you about the thermal characteristics of B-G431-ESC1 Motor Control evaluation board.I purchased it few weeks ago and started to play with six step for beginning and later FOC algorithms. I observed on my board that if power supply V+ 18-20V is active and PWM outputs are switching, of course deadtime is set to ~500ns, board running at 170MHz the PCB temperature reaches  ~50 °C or even more. The temperature is quite uniform. The DC/DC itself produces heat by switching and the power stage too, but for me seems to be a little to much. Is it normal or something is failed on the board? I removed the DC/DC converter and provided the 10V from external supply, the situation is similar. PWM outputs disabled. In that case the heat is produced by DC/DC only. Is that normal? I did rough calculation based on datasheet and for me it looks to be too much for roughly 100mA output current. Additional heat generated by 3-phase power stage itself when PWM

Can X-NUCLEO-IHM09M2 (adapter board) connect with NUCLEO-H755ZI-Q (controller board) using male and female connector(without flying wire)? 

I am working on a project to drive a door using a PMSM motor in position control mode.When I change the shunt resistor value in the Current Detection step of MCW, the overcurrent protection threshold remains fixed (7A) and does not update accordingly.When the shunt resistance value is modified, isn’t the overcurrent protection threshold expected to update too?Screenshots are attached.Thanks in advance for your help. Details:ST MCW Ver            : 6.4.0STM32CubeIDE Ver : 1.19.0Driving algorithm       : FOCControl board            : Nucleo-G474REPower board              : STEVAL-IHM023V3Bridge                        : X-NUCLEO-IHM09M2

I am a new user looking to configure the STEVAL-IPM30B evaluation board to drive a three phase dc motor.  I am uncertain which of the many STM32 boards I require.  Also, what type of cable is needed to connect the two boards?  My application requirements are basic on and off control of the motor at different speeds with open loop operation (I am using a three phase stepping motor).  

Hello everyone,I want to understand to clear my mind about regenerative brake MC library. I dont have ossiloscope.Assume P-NUCLEO IHM03. I am using it with different motor with HALL sensors with load. in speed control -> MC_ProgramSpeedRampMotor1_F(targetspeed, rampduration);   TO MC_ProgramSpeedRampMotor1_F(0, rampduration);Now we get energy from Motor to Battery, right?But because of no control of this energy, if Voltage is too high then can gives damage the battery.1-let me know. Can MC library observe the Voltage and if it is too high direct it to Motor coils to consume like low side pwm turn on( as much as I know in this case entire energy consumed in motor), or we gonna do it manual, if it manual how we gonna do that(function name?)  2- assume we have high power resistor parallel to VBus(as much as I know this resistor connect like that ?), In this case ,how we gonna direct the current to Resistor.(function name)Please make my mind clear abou

Hello,I am controlling my motor with the Hall effect sensor first. I am not using any auxiliary sensor. I am able to control my motor correctly, and I can visualize the angle from the Hall sensor. I need to evaluate the number of turns the motor makes and be able to reset this counter to zero at the start. Thank you.

I'm learning BLDC control using the EVSPIN32G06Q1S1 and MCSDK 6.4. The inner current loop is implemented in hardware. The current feedback goes to an op-amp PI controller (I think?),then is compared with a reference voltage.The reference voltage level depends on the TIM17 PWM duty cycle.The comparison result goes to TIM1 ETR. There is no documentation for this. I need a manual or design guide for selecting the capacitor and resistor values in the PI controller.  I found a description of current loop control in X-CUBE-SPN7,UM2124 section 3.3.1 “Current Mode Control,”but it is not included in the MCSDK or EVSPIN32G06Q1S1 documentation.The principle looks similar to peak current mode control in switching power. Can anyone confirm this or provide me with the correct documentation?After all, UM2124 is not intended for the EVSPIN32G06Q1S1.Thanks
